Product Description

S and SH type pumps are single-stage, double-suction split-type centrifugal pumps, used for pumping clean water and liquids with physical and chemical properties similar to water.
The head of this type of pump is 9 meters to 140 meters, the flow rate is 126m3/h to 12500m3/h, and the maximum temperature of the liquid must not exceed 80°C. It is suitable for factories, mines, urban water supply, power stations, large-scale water conservancy projects, and farmland drainage and irrigation. etc., 48SH-22 large pumps can also be used as circulation pumps in thermal power plants.
Pump model meaning: such as 10SH-13A
10—The suction inlet diameter divided by 25 (that is, the pump suction inlet diameter is 250mm)
S, SH double-suction single-stage horizontal centrifugal water pump
13—Specific speed divided by 10 (that is, the specific speed of the pump is 130)
A indicates that the pump has been replaced with an impeller with a different outer diameter.

Performance parameters

SH single-stage double-suction large-flow open centrifugal pump parameter range and model meaning:
Flow (Q): 110-12020m3/h
Lift (H): 8-140m
Model: 6-SH-6-A
6-Pump inlet diameter is 6 inches
SH-horizontal single-stage double-suction split pump
6-1/10 of the specific speed of the pump is circular
A-impeller outer diameter SH type medium
Open and disassemble the pump
SH type single-stage double-suction large-flow medium-opening centrifugal pump structural features:
Compact structure: beautiful appearance, good stability and easy installation.
Smooth operation: The optimized design of the double-suction impeller minimizes axial force and has blade profiles with excellent hydraulic performance. high efficiency.
Shaft seal: Choose mechanical seal or packing seal. Guaranteed to run for 8,000 hours without leakage.
Bearings: SKF and NSK bearings are selected for smooth operation, low noise and long service life.
Installation form: No adjustment is required during assembly and can be used according to site conditions. Discrete or horizontal installation.

Assembly and disassembly of SH single-stage double-suction large-flow intermediate-opening centrifugal pump:

1. Assemble the rotor components: install the impeller, shaft sleeve, sleeve nut, packing sleeve, packing ring, packing gland, water retaining ring, and bearing. Install the parts on the pump shaft in sequence, put on the double-suction sealing ring, and then install the coupling. Axis.
2. Install the rotor component on the pump body, adjust the axial position of the impeller to the middle of the double-suction sealing rings on both sides for fixation, and tighten the bearing body gland with fixing screws.
3. Install the packing, put in the middle mouth paper pad, cover the pump cover and tighten the screw tail pin, then tighten the pump cover nut, and finally install the tomb gland. However, the packing should not be pressed too tightly, which will cause the bushing to heat up and consume a lot of power, nor should it be pressed too loose, which will cause a large amount of liquid leakage and reduce the efficiency of the pump.
After the assembly is completed, turn the pump shaft by hand without friction and the rotation will be smooth and even. When disassembling, follow the reverse order of the above assembly.
